  2. 21. Image Analysis and Visualization of the Human Mastoid Air Cell System

    Author : Olivier Cros; Michael Gaihede; Hans Knutsson; Magnus Borga; Torbjörn Ledin; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : From an engineering background, it is often believed that the human anatomy has already been fully described. Radiology has greatly contributed to understand the inside of the human body without surgical intervention. READ MORE

  4. 22. Radiation dose-, contrast media- and image quality optimization in computed tomography

    Author : Daniel Thor; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Computed tomography (CT) was introduced to medicine in the early 1970s, which brought slice imaging into wide use for the first time. Today, CT is an essential part of radiological diagnostics, and is used for a wide range of clinical applications. One downside of CT imaging is the health risks related to the ionizing radiation.

  5. 23. Structural properties of the mastoid using image analysis and visualization

    Author : Olivier Cros; Michael Gaihede; Hans Knutsson; Bernard Ars; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The mastoid, located in the temporal bone, houses an air cell system whose cells have a variation in size that can go far below current conventional clinical CT scanner resolution. Therefore, the mastoid air cell system is only partially represented in a CT scan. READ MORE

  6. 24. Elbow kinematics : studies of the elbow joint under normal conditions and after joint replacement

    Author : Anne Ericson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Total elbow arthroplasty (TEA) is used for treatment of patients with severe pain and disability due to reumatoid arthritis. Long term results are not as good as for hip and knee replacements. READ MORE

  7. 25. Dual-energy imaging in stroke : feasibility of dual-layer detector cone-beam computed tomography

    Author : Fredrik Ståhl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Dual-energy computed tomography (DECT) is increasingly available and used in the standard diagnostic setting of ischemic stroke patients. For stroke patients with suspected large vessel occlusion, cone-beam computed tomography (CBCT) in the interventional suite could be an alternative to CT to shorten door to thrombectomy time.
